Chemical Bonding and Molecular Structure

After understanding the assertion and reason, choose the correct option.

Assertion : In the bonding molecular orbital (MO) of $\ce{H2}$, electron density is increased between the nuclei.

Reason : The bonding MO is $\psi_A+\psi_B$, which shows destructive interference of the combining electron waves.
